THOMAS THRELFALL, OF SAN FRANCISCO, CALIFORNIA.

BOTTLE-CORKER.

SPECIFICATION forming part of Letters Patent No. 245,326, dated August 9, 1881.

Application filed April 8, 1881. (No model.)

T 0 all whom it may concern:

Be it known that I, THOMAS THRELFALL, a subject of the Queen of Great Britain, and residing at San Francisco, in the county of San Francisco and State of California, have invented a new and useful Bottle Corker, of which the following is a specification.

The object of my invention is to provide a hand-bottling machine adapted to fit the neck of bottles of variable size and height. I attain this object by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a side elevation. Fig. 2 is a sectional side elevation. Figs. 3 and 4 are respectively an elevation and plan, showing a modification.

Similar letters of reference refer to similar parts throughout the several views.

The cylinder A and piston B ofmy machine are constructed much in the usual manner, and the cylinder is provided with a rabbet, C, for receiving the cork.

To the upper end of the piston-rod or plunger B is pivoted the operating-lever E, and to the outer end of this lever is connected, by a pin, the link F, which extends downward to the arm or bracket G of the corking-cylinder, to which it is connected by a pin, in the same manner as connection is made with the lever, so that when the lever is raised orlowered the link will assume a more vertical or inclined position, accordingto the length of the stroke imparted to it.

From the lower face of the bracketGr extends a half-round arm or are, H, in line with the mouth of the corking-cylinder, and which is adapted to receive the neck of the bottle to be corked.

The outer end of the bracketG is pierced to receive a stationary rod or spindle, I, which permits the machine to be moved to the right or left, or raised or lowered, so as to adapt it to the different heights ofbottles, and in which position it is held by the nut and set-screw l.

A coiled spring, J, is placed around the spindle, the lower end of which rests upon the arm or bracket G, while the upper end is confined by the set-screw and nut K. The downward pressure from this spring serves to keep the machine in position when the neck of the bottle is received by the curved arm.

In the modification shown in Figs. 3 and 4 the vertical standard or rod and spring are dispensed with, and the arm L may be grasped by the hand or attached by the lug or strap M to any convenient stationary table or platform.

In practice the piston is raised by the leverarm and the cork placed in the rabbet, when the piston is forced down and presses the cork home.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-

The combination and arrangement of the corking-cylinder, piston, lever-arm, and connecting-link F with the bracket provided with the arm or are H, adapted to receive the neck of a bottle, constructed and arranged to operate in a fixed ormovable manner, substantially as herein set forth and specified.

In testimony that I claim the foregoing I have hereunto set my hand and seal this 12th day of March, 1881.
